Upon receipt of sufficient evidence that a lawyer who practices law in this State poses a threat of harm to his clients or the public, the State Disciplinary Board may conduct an Audit for Cause with the written approval of the Chairman of the Investigative Panel of the State Disciplinary Board and the President-elect of the State Bar. Before approval can be granted, the lawyer shall be given notice that approval is being sought and be given an opportunity to appear and be heard. The sufficiency of the notice and opportunity to be heard shall be left to the sole discretion of the persons giving the approval. The State Disciplinary Board must inform the person being audited that the audit is an Audit for Cause. The failure of a lawyer to submit to an Audit for Cause shall be grounds for discipline pursuant to Standard 65.5.
